Abstract

This paper gives the principle of design and the operation concerning the Spectrum Measure Unit of Algae and Suspension. Many series of measurements were made with the meter which uses the wavelength from 400-760nm. Algae and suspension in the water can be discerned by the Discrimination of Algae and Suspension with Optical Spectral. The instrument can real time carry out red tide monitoring. The experimental results from actual underwater applications are presented in this paper.
